Subject: [PATCH 3/3] userdiff: learn the C++ spaceship operator
Message-ID: <df66485e7f019dd81f53f73fd3772bf0b678059d.1633589461.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.1054.git.1633589461.gitgitgadget@gmail.com>

From: Johannes Sixt <j6t@kdbg.org>

Since C++20, the language has a generalized comparison operator. Teach
the cpp driver not to separate it into <= and > tokens.
